By 2 a.m., crews will slice the bridge in half lengthwise. Later, hoe rams, which are giant, jackhammer vehicles, will do their jobs and take the bridge apart.

In the meantime, city leaders want us to do our jobs.

"Stay the hell away from the 405," emphasized L.A. City Councilman Paul Koretz.

Caltrans will begin closing on-and off-ramps of the 405 in both directions between the 10 and 101 freeways starting 7 p.m. Friday.

The freeway will be closed at midnight and demolition will take place around the clock for 53 hours, with the stretch expecting to reopen at 5 a.m.
